List variables should not be multiplied when modifying variables in the daily plan view

Current Situation

A workflow W1 makes use of a list variable L1 with n properties. A schedule S1 is defined and W1 is assigned S1. The schedule defines k entries for the list.

When the daily plan for S1 is created, the orders do have the correct variables as defined in the schedule order parameterization.

When the variables for a planned order are modified using "Modify Parameterisation" in the Daily Plan view, the order will be stored with a list that has n*k entries.

Desired Behavior

With the given configuration described above, when the variables for a planned order are modified using "Modify Parameterisation" in the Daily Plan view, the order should be stored with a list that has k entries.
